Lady Gaga ended a lawsuit with producer and ex-boyfriend Rob Fusari last September after a legal battle over copyrights was launched in March. Fusari sought a monetary deal for allegedly co-writing some of the pop star's hits, inventing her stage name and helping launch her into stardom.

Like any good reporter, Anderson Cooper is good at getting people to relax and open up, but Lady GaGa may have bested the CNN newsman.

At the end of a "60 Minutes" interview, the international pop icon went drinking with Cooper and got him tipsy.

"We actually ended up that day in a pub in London drinking Jameson, which I don't really drink," the anchor told The Insider. "So she got me to drink, like, two of them. And by the end, I was ready to have the interview be over, because I really sort of couldn't ask anymore questions."

Cooper sounds a bit like a lightweight, but he's definitely a "Little Monster." The hour-long show isn't slated to air until Grammy night 2011, but the journalist is already gushing about the Grammy-winning singer.

"She's obviously a fascinating person," he told The Insider.

The high-profile drinking buddies got together on a few occasions for the Q & A, and Cooper added that the show was a great way to get to know the headline-making performer.

"What's great about '60 Minutes' is you spend a lot of time with the person you're profiling. So to be able to spend a couple of weekends with [Lady GaGa] in various paces over the course of several months, it's really cool. And it's really interesting…I'm learning stuff about her I never saw before."
